Description

AT396 355 B

The invention relates to a rack storage system with a central rack device and a split outer rack device concentrically rotating around it, which enclose an intermediate space between them, and a rack operating device which can be displaced along horizontal and vertical guide devices between the rack devices. 5 In a shelf warehouse known from DE-PS 20 31 442 of the category according to the application, the horizontal guide device and part of the vertical guide device are arranged above the shelf warehouse. The height of a building envelope surrounding the rack storage must therefore be designed for the height of the parts of the storage and retrieval device projecting beyond the storage racks. Furthermore, the shelf construction must have a high load-bearing capacity, since in addition to the payloads, the weight of the shelf operating device must be borne entirely by the 10 shelves.

The present invention is based on the object of avoiding the disadvantages mentioned above and of creating an economical rack storage which, even with a not very large storage throughput, enables a favorable utilization of the available space even in a small area.

This object of the invention is achieved in that the horizontal guide device is designed such that it can be moved vertically 15 and is adjustably mounted on the fixed vertical guide device in the space between the central rack device and the outer rack device of the rack warehouse and in that a horizontal guide device that can be moved vertically along the fixed vertical guide device horizontally movable carriage is arranged.

As a result of this surprisingly simple solution, a large storage area is served with a continuous guide device and thus with a single rack operating device

In addition, there is the advantageous effect that, in the embodiment of the rack operating device according to the invention with the guide devices, the outer rack device can be designed essentially without interruption and z. B. a shelf is adapted as a transport lock for the outsourced and stored items. This means that additional storage space is gained and, in addition, a greater stability of the racking device is achieved.

According to a further advantageous embodiment, it is provided that the vertical guide device for the rack operating device can be moved vertically and is adjustably mounted on the fixed horizontal guide device in the space between the central rack device and the outer rack device of the rack warehouse, and that the vertical guide device on a along the fixed horizontal 30 Guide device horizontally movable carriage is arranged

As a result, the moving masses for the storage and retrieval unit for horizontal travel can be kept low, which results in a higher travel speed and thus shorter access times for operating the rack warehouse.

In addition, there is the advantageous effect that, in the embodiment of the storage and retrieval device with the guide devices according to the invention, the outer storage device can be designed essentially without interruption and z. B. a shelf is adapted as a transport lock for the outsourced and stored items. This means that additional storage space is gained and, in addition, greater stability of the racking device is achieved. But it is also possible that the fixed vertical guide device is supported on the footprint and / or 40 fixed on the shelf device, which gives the possibility of rigid arrangement of the guide device of the shelf operating device using the support elements of the shelf storage, which with less construction and Manufacturing costs for the horizontal and vertical guide devices of the rack operating device can be found to be sufficient and moreover the effort for the production of the rack operating device can be reduced by the fixed arrangement. It is also advantageous if the stationary horizontal guide device is supported on the contact surface and / or on the shelf device, since this allows the construction and stability of the central shelf device to be used for storing the shelf operating device.

According to a further embodiment of the invention, it is provided that the outer rack device is designed as a continuous circular ring, whereby continuous operation by 360 degrees is possible through the 50 rack operating device and with a single rack operating device for the operation of the shelves it is possible to get by. At the same time, the storage and retrieval device is secured against entering the carriageway by the outer racking device.

Furthermore, it is also possible for the central racking device to be designed with a prismatic cross section, the axis of symmetry of which runs vertically, and for the outer racking device to be formed by a hollow prism, so that it can be found to be sufficient with linear guideways.

Further advantageous developments are characterized in the further subclaims

For a better understanding of the invention, it is explained in more detail below with reference to the exemplary embodiments shown in the drawing figures

7 shows the control station of the storage and retrieval device with a schematic circuit diagram 10 associated therewith of the control device for the storage and retrieval device.

In Fig. 1, a shelf storage (1) according to the invention is shown in a highly simplified schematic representation. This shelf storage (1) comprises a central shelf device (2). This is surrounded by an outer shelf device (3), of which a part is not shown in the drawing for better clarity, but which is usually as a closed circular ring or as an oval or at least as a substantially closed circular ring or oval over an angular range of z . B. surrounds about 270 degrees the central shelf device (2)

A shelf operating device (4) is arranged between the outer and the central shelf device (3) or (2), which along a vertically movable horizontal guide device (5 ') and a fixed vertical guide device (6') into an approximately annular space ( 7) is adjustable. In the exemplary embodiment shown, the horizontal guide device (51) has, as a horizontal roadway, a supporting element, for example in the manner of a box girder (8), on which a carriage (10) supporting a transport platform (9) is guided. A rack (11) can be installed as part of a feed device in a surface of the box girder (8) facing the slide (10), which cooperates with a gear (12) of the drive device (13) mounted on the slide (10). The movement of the rack operating device (4) along the horizontal path of the horizontal guide device (5 ') can be controlled and monitored by a control station arranged on the transport platform (9) with a seat (14) and a control device (15) 25 arranged in this area . This enables access to the transport platform (9) over the entire outer circumference of the central racking device (2) and the inner circumference of the outer racking device (3). In order to be able to operate the shelves (16), (17) and (18) one above the other in the vertical direction, the box girder (8) of the horizontal guide device (5 ') is mounted on guide columns (19) of the vertical guide device (6' ) slidably mounted. A lifting drive (20), which has a cable winch (21) with a drive motor (22), is used to adjust the height of the box girder (8) with the transport platform (9), with the free end of the support cables (23) facing away from the cable winch (21) the box girder (8) are motionally connected. By actuating the drive motor (22), the box girder (8) and thus the transport platform (9) can each have 35 shelves (16), (17) or (18) of the outer shelf device and / or one with shelves (24) to (26) aligned position. This permits trouble-free removal or storage of objects, such as transport containers (28) or boxes (29) or storage containers (30) for small parts arranged on pallets (27), which are preferably arranged in the central racking device (2) . 40 The possibility of storing smaller parts or small parts in the central racking device (2) and storing larger parts in the outer racking device (3), for example goods deposited on pallets or transport containers, enables the available circular or segmented sections Parking space in the central or outer shelf device (2) or (3) can be used cheaply.

For better clarity, the 45 respective shelves were only partially shown in the schematic representation of the shelf storage (1). At the same time, the drive and the guiding devices were shown in a significantly simplified manner. However, as can be seen from the drawing, massive uprights are provided at certain intervals, to which the individual plate-shaped shelves are attached. The embodiment and construction of the shelf storage as such is freely selectable and it is also possible, for example, to use spaced-like framework elements between which the individual 50 shelves are hung.

Furthermore, as can be seen from this schematic representation, it is advantageous if the guide column (19) of the vertical guide device (6 ') are arranged within the outer envelope of the central rack device (2). This enables a gap-free transition between the transport platform (9) and the individual shelves (24) to (26) to be achieved. 55 A shelf storage (1) according to the invention is shown in FIGS. 2 and 3. From these representations it can be seen that the shelf warehouse (1) can be erected as an independent building object, for example in the manner of a silo, independently of the existing structures, the connection to existing buildings (31) being possible via covered bridges (32). Access takes place from these bridges (32) or, if the shelf storage (1) directly abuts a building (31), as shown in the left half of FIG. 2, via parts 60 of shelves (33) and (34 ), which serve as lanes to the transport platform (9) of the storage and retrieval device (4), which can also be used to bridge any level difference from storeys (35). It is possible to do this, for example in the area of such bridges -3-

AT 396 355 B (32) or storeys (35) between stacked shelves (33) to provide a greater height (36) than corresponds to a vertical distance between the shelves (33) in the storage area, in order to gain access by means of mechanical stacking devices (37 ), for example to enable forklifts or pallet trucks. As indicated in the area of the shelf (33), the access from these shelves to the shelf operating device (4) is by means of a gate (38), for example a lifting gate, which, with a lifting cylinder within guides, provides access to the transport platform from the lines drawn in full lines ( 9) preventable closed position can be adjusted in a raised open position drawn in dashed lines, closable. The guides for the gate (38) are attached to the outer shelf device (3). However, it is of course also possible to use a lamellar roller shutter door (38). Regardless of the embodiment of the gate (38), it can only be opened when the transport platform (9) is in the aligned position with the shelf (33) or (34). As can be seen in particular from the top view in FIG. 3, the access width to the transport platform (9) in the area of the bridge (32) and the shelf (33) extends only over an angular range of the entire circumference, the immediately adjacent areas of the shelf (33) for storing goods, for example boxes (39), can be used. From this illustration it can also be seen that with a suitable choice of the size of the products or containers stored on the central shelf device (2) or the outer shelf device (3), the storage space is used well. The spaces between the individual boxes (39) and the storage containers (30) can, as can be seen from the left half of FIG. 3, serve to arrange the support and support elements (40). As shown schematically in FIG. 2, these consist of lattice truss constructions in which the individual shelves (33), (34) or, of course, also the shelves (24) to (26) and (16) to (16) to indicated schematically in FIG (18) preferably suspended at interchangeable heights or can be fastened by means of screws. This support and support elements (40) can simultaneously as a support structure for an outer jacket (41), z. B. from segment-like side-by-side sandwich panels and a roof (42) are used, so that the stability of the spatially stiffened by the shelves support and support elements (40), which thus form a spatial framework, are used as a basic framework for the shelf storage. Through this use of the support and support elements, the total costs of such a rack warehouse (1) can be reduced compared to the previously known high rack stores. This enables the economic use of the front of such a rack warehouse (1) even for smaller companies, for example medium-sized or larger commercial companies.

As can also be seen from the illustration in FIG. 2, the shelves in the central shelf device (2) and in the outer shelf device (3) can have different heights (43) and (44), preferably the height (43) in the central shelf device (2) is less than in the outer shelf device (3), so that these can also be easily adapted to the usually lower height of smaller storage containers (30). The operator (45) on the rack operating device (4) is able to operate several such shelves (24), (25), (26) arranged one behind the other at a short distance, with the transport platform (9) being steplessly accessible vertical direction, an optimal grip height for the operator (45) for removing and storing goods can be achieved.

Furthermore, as can be seen from FIG. 3, the shelf operating device (4) can form a circular ring section which has an opening angle (46) of greater than 90 degrees, for example 120 degrees, the seat (14) for the operator (45 ) can be arranged approximately in the middle of the circular ring section, so that goods or storage containers (30) or boxes (39) or pallets (27) can be placed on both sides of the transport platform (9) in order to achieve an optimal movement cycle of the rack operating device (4) to achieve. 2 and 3, an annular box girder (8) also serves as the horizontal guide device (5 '), the vertical guide device (6') of the vertical guide device (6 ') being arranged along guide columns (19) arranged inside the outer circumference of the central rack device (2) is adjustable. The lifting drive (20), see FIG. 2, is arranged on the top shelf of the central shelf device (2) below the roof (42) and, as shown for example in FIG. 1, can comprise a cable winch or, for example, also parallel to the Guide columns encircling chains exist. A control device (15) arranged on the transport platform (9) in the region of the seat (14) is used to control the storage and retrieval device (4).

In the selected embodiment, the vertical axes of symmetry (48) of the outer and the central shelf device (3) or (2) run coaxially and the inner diameter (49) of the outer shelf device (3) corresponds approximately to the distance which results from the outer diameter (50) of the central shelf device (2) plus twice the width (51) of the space (7) between these two shelf devices (2), (3), the width (51) essentially being one in the radial direction of the shelf store (1 ) corresponds to the measured width of the transport platform. The transport platform (9) must be provided with a protective grille in its end regions (52) in order to ensure sufficient safety for the operator (45).

Two slides (8 ') are arranged on the guide columns (19) within the clearance of the rack operating device (4), which are connected to the box girder (8) in their area facing away from the guide columns (19), and a slightly larger inner diameter (54 ) have as the outer diameter (50) of the central shelf device (2). -4-

AT 396 355 B

Furthermore, if the guide columns (19) are arranged within the outer circumference of the central racking device - as can best be seen from FIGS. 2 and 3 - there is an almost gap-free transition between the transport platform (9) and the shelves in the central racking device (2nd ) reached

4 and 5, another embodiment of a shelf storage (1) is shown, in which a central shelf device (2) forms an essentially rectangular cross section and an outer shelf device (3) forms a hollow prism with an approximately likewise rectangular cross section. Of course, it is also possible to choose a square cross section instead of the rectangular cross section.

Between the central and the outer rack device (2), (3) there is an intermediate space (55) in which a rack operating device (56) can be moved on a guide rail (57) which runs around the base in the intermediate space. A support rail (58) can be assigned to this guide rail (57) in the upper end region of the shelves, as indicated by a partial region of the intermediate space (55). The storage and retrieval unit (56) consists of two vertically extending bars, which are simultaneously designed as guide columns (59). As can be seen better from FIG. 5, a toothed rack (60) of a lifting drive (20) is arranged in the peripheral region of the guide columns (59), with which a toothed wheel (12), which is coupled to a drive motor (61), meshes . By acting on the two drive motors (61), a transport platform (62) can thus be moved up and down in the vertical direction between the outer and the central rack devices (3) and (2).

To move the storage and retrieval device (56) along the guide rail (57), the latter is provided with two trolleys (63) which can be pivoted about vertically extending axes and which grip guide rails (64) on all sides around a rail head (65). As can be seen from the illustration shown in FIG. 4, it is possible with these two swiveling undercarriages (63) to follow very tight curve radii of the guide rail (57). In order to find the minimum possible depth of shelves (66), (67) of the outer and central shelf devices (3) and (2), the transport platform (9) must run transversely to the longitudinal direction of the guide rail (57) Provide plate parts (68), (69) which can be extended by means of drives (70) from the shown retracted transport position into the loading position indicated by dashed lines. As a result, the width of the transport platform (9) can be reduced while driving through the curves, so that the space (55) to be kept clear between the rack devices (2), (3) can be kept to a minimum. Furthermore, it is also possible to keep free the space required for fully extended transport plate shapes over the course of the height of the shelf device only in the region of some of the stacked shelves, so that the curves can only be traversed in these regions. The areas of the shelves located in the curved area of the guide rail (57) can be operated, for example, by means of plate parts (71) which can be extended in the direction of travel of the shelf operating device (56), as shown with the dash-dot line in FIG. 5. The drives (70) for the plate parts (68), (69) and (71) can be locked via the control device in such a way that they can only be extended when the rack operating device (56) is in straight regions of the guide rail and must be retracted before continuing, or retracted automatically.

However, it is also possible, for example - as shown in the right-hand part of FIG. 4 with dash-dotted lines - to form the transport platform (9) in a size corresponding to a distance (72) between the outer and central shelf device (3) or (2), in order to enable the overlap between the transport platform (9), which is shown in dash-dotted lines, and the shelves in the corner area, the curves can only be avoided if the transport platform (9) is between two shelves and the pallets (27) are arranged at a greater distance from the edge of the outer and central shelf device (3) or (2) facing the transport platform (9) in order to avoid damage to the stored objects or pallets.

6 shows a rack operating device (4) which has a cabin (73) which can be adjusted by means of vertically movable guide devices (6). In this cabin (73) there is a transport platform (9) on which a seat (14) for the operator and a control device (15) assigned to the operator are arranged. Furthermore, a transport device (75), which is adjustable transversely to a direction of travel indicated by a double arrow (74), is fastened in the cabin on the transport platform (9), the fork prongs (76) of which are manipulated telescopically transverse to the one indicated by the double arrow (74) for manipulating pallets Direction of travel are adjustable by means of a drive (77). The height of the fork tines (76) can be adjusted relative to the transport platform (9) using a lifting drive (78).

The height of the cabin (73) can be adjusted, for example, by means of a telescopic cylinder (79) in a support frame (80) of the rack operating device (4) in the direction of a double arrow (81). To move along the guide rail (57), a drive motor (84) is assigned to each of two undercarriages (82) which are arranged on the support frame (80) such that they can pivot about vertical axes (83) - as shown in the drawing on the right undercarriage .

7 shows a block diagram of a control device (15) for a storage and retrieval device (4), of which only a part of the transport platform (9) with the seat (14) arranged thereon is shown. The seat (14) is, for example, via spring elements ( 85), e.g. B. coil spring supported on the transport platform (9) Between the spring elements (85) is a monitoring element (86), z. B. a button that acts as a limit switch, arranged. If the weight of an operator loads the seat (14), -5-

Claims (14)

AT 396 355 B the spring elements (85) are pressed together and the monitoring element (86) or a swivel lever of the same is pressed down by a support plate (87) of the seat (14). In this position, a signal is sent to a control device (88). This control device (88) is connected to a pulse timer (89), which also delivers corresponding time pulses to a control unit (90), which is used, for example, for drive motors (84) or pressure medium pumps (91) - for example, for loading the telescopic cylinders (79) in Fig. 7 - actuators (92), (93) and an emergency stop button (94). Further actuating members (95) serve to control different functions of the rack operating device (4), for example to actuate the drives (77) or lifting drives (78) of the fork tines (76) of the transport device (75). A safety device (96) with a button (97) is also arranged in the area of the seat (14). The function of the control device (15) is now such that when the monitoring element (86) is acted on, because the operator has taken a seat on the seat (14) and at the same time actuates the button (97) of the safety device (96) in the manner of a two-hand operation the function of the actuators (92), (93) and (95) of the control unit (90) is released. Time pulses are emitted successively via the pulse timer (89) to the control device (88) or the safety device (96), these time pulses being used for a safety driving circuit which only interrupts the action on the button (97) within a certain period of time and this is actuated again or the seat (14) is loaded and unloaded, the functionality of the control unit (90) is maintained. If, for example, the operator briefly closes the button (97) or the monitoring element (86) in a non-authorized manner due to permanent loading, the function of the control unit (90) is interrupted after a predetermined period of time.
